What happens when someone lets go of the button on an electric doorbell? The electromagnet gets stronger. The circuit is broken and the electromagnet turns off. The current moving through the circuit changes direction. The metal striker hits the bell.
Answers
Answer:
It's actually C. The current moving through the circuit changes direction.
Explanation:
Electromagnet: It is a temporary magnet. When the iron rod is wounded by the coils and the current is passed through it then it becomes magnetized and behaves like a temporary magnet as long as the current flows through it.
When you push the button of a doorbell then the circuit completes and the current starts flowing through the circuit. The electromagnet is activated.
It causes a buzzer to go off. The hammer strikes the bars which creates sound.
When you let go, it will stop making a sound by the circuit stop flowing.
Hope this helps. Have a nice day.
